DRAFT-ATTACHMENT FORDISK NARROW.

Specification of Letters Patent.

Patented July 24, 1906.

Application filed January 2,1906. Serial No. 294,272.

To all whom it may concern:

Be it known that I, STEPHEN H. GARST, a

citizen of the United States of America-residing at Detroit, inithc county of Wayne and State of Michigan, have invented certain new i and useful I niprovements in Draft Attachments for Disk llarrews, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relatrs to draft attachments particularly designed for use in connection with disk barrows, but applicable also to other agricultnral machinery and it is the object of the invention to obtain aconstruction in which a turn may be made b r the team in a smaller space than Wl'lGlB tie usual drafttongue is omploy'cd.

The invention consists in the I eculiar con. struction, as hereinafter set fortif.

In the drawings, liigurc 1 is a plan view of the draft mechanism. Fig. 2 is a side elevation of the forward part of the construction illustrated in Fig. 1. V

I A is the frame for the disk harrow or other agricultural implement. (Not further illustrated). in place of the usual draft-tongue commented to said frame I. provide a stubtonguo B, which is secured to the frame A, projecting forward therefrom and preferably strengthened by a diagonal brace C. The for ward end of the stub-tongue B is supported upon a swivcl-tru ck D, which is provided with a forwardly-extending arm E, to which the whifiletrecF is connected. Thus the truck will I mcnt of the clcvis to'thc stub-tongue B and comprising a link, which is apcrturcd at op positc ends andis sleeved upon the vert cal portion a of the arm E anda vertlcal rod 1,

which forms the swivel of the truck: This rod I is preferably secured to a casting J,-

which is sockotcd to receivethe same, and

said casting forms thcjournal for the truck;

axle d and a bearing for the attachment of the arm E. The link H engages the vertical rod i between fnrcations 1n the forward end of the stub-tongucB, which latter is preferably formed of an end member 0, which is bifurcated, and separated bars j, which extend back to the frame.

With the construction just described it will be understood that the connection in the direct line of draft extends from the frameA to the whiiiletree F, said connection comprising a stubton'gue B, with its bifurcated member a, the link H, and the clevis G. This draft connection is maintained in each adj ust ment of the clevis G, as the link H is slidablc upward or downward upon the bar a and'also upon the bar I and being secured'to the lat ter by a set-screw K. At the same time the rod l is free to turn in the bifurcated bearing of the member a, so as to permit of the swivel .of the truck. Thus in use the team attached to the whifiletrcc can take a short turn and in so doing will swing the arm E and turn the truck 1), while at all times-the draft is directly through the link Hand stub shaft B.

What I claim as my invention is' 1. A draft attachment for agricultural instruments comprising a stub-tongue, a truck for supporting the forward. end of said tongue tending end portion, a link connecting said swivel-shaft and the upward. extension of said draft-arm and vertically adjustable thereon and a clcvis vertically adjustabl secured to said upward. extension of said dralt-arm above and below said link, for the purpose described.

3. A draft attachnient for agricultural implemcnts comprising a stub-tongue, a bifurcatod bearing at the forward end thereof, a-

vertical shaft swivclcdinsaid .ljiifurcated bearing, a truck supporting said shaft and. draftarm extending forward from said truck and upward parallel to said: swivel-shaft a clevis having a bifurcated vertical y adjuetable In testimony whereof I afiix my signature bearing engaging the award extenslon of. m presence of twowltnesse's';

- said draft-arm anda lin sleeved upon said draft-arm and .upon said swivel-shaft inter- STEPHEN 5 mediate the fureations of said'stub-tongu'e Witnesses:

and clevis and vertically adjustable there- W. E. KIRBY,
